- HEATING AND VENTIILAYTING APPARATUS.

SPECIFICATION forming part of LettersPatent No. 402,217, dated April 30, 1889.

Application filed January 10, 1889- .To aZZ whom/ it may concern:

Be it known that I, WILLIAM S. ZIEGLER, a citizen of the United States, residing at Butler, in the county of Butler and State of Penn-' sylvania, have invented certain new and useful Improvements in Heating and Ventilating Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to aheatin g and ventilating apparatus designed for heating or ventilating different apartments in buildings.

The object of the invention is to provide a device of this character whereby a portion of the heat provided in one apartment may be utilized for heating one or more of the other apartments in the same building.

A further object of the invention is to provide a simple and improved apparatus of this class which will possess advantages in point of inexpensiveness, durability, and general efficiency.

To this end the invention consists, substantially, in providing, in connection with stationary receiving and delivery pipes, aremovable drum connecting the same and adapted to be quickly and readily attached to or removed therefrom.

In the drawings, Figure 1 is a side elevation of the interior of a building, showing the application of my invention. Fig. 2 is a vertical sectional View. Fig. 3 is a detail perspective view of the drum and connecting-elbows detached. Figs. 4 and 5 are detail sectional views.

Corresponding parts in the figures are de- Referring to the drawings, A designates a chimney provided with a fire-place, B, within which is preferably disposed a grate, C.

D E designate, respectively, the receiving and delivery pipes, the former of which, or the cold-air pipe, extends from the cellar or outside of the building to the fire-place,while the delivery or hot-air pipe extends from the opposite side of the fire-place to one or more of the other apartments of the building. The outlet end of the delivery-pipe is provided ment other than the one in which the fire is Serial No- 295,997. (No model.)

located is to be heated branch pipes are run from the delivery-pipe to the same, and each of said branch pipes is also provided with a register.

In the present instance I have shown the apparatus as applied for heating the-apart ment directly above that in which the fire is located. In this case the delivery-pipe is preferably built in the chimney, and is provided at its upper ends with an elbow, F, connected with a register, G, at the side of the chimney. The elbow may, however, be turned in the opposite direction to connect the pipe with the fire-place uponthat floor, inwhich case the fire-place will be closed and provided with a register. The opposing ends of the receiving and delivery pipes at the opposite sides of the fire-place B project within the latter, and are each provided with a circumferential flange, (l 6, respectively, (which are in practice about half an inch from the extreme ends of the pipes,) said flanges being adapted to fit closely against the side walls of the fire-place.

H designates a cylindrical drum, which is adapted to connect the receiving and delivery pipes and fit the space between the opposing ends thereof, said drum traversing the grate when in position. In order to connect the drum with the pipes, the ends of the former are exteriorly screw-threaded, and upon said ends are disposed connecting sleeves I I. These sleeves are provided interiorly at one end with screw-threads 11 "Awhile the other end is smooth or not threaded, as shown at 11 2', corresponding in diameter and adapted to receive the opposing ends of the pipes. It will be obvious that the smooth interior end of each of the sleeves is of suffic-ient diameter to permit the same to pass over the threadsupon the drum. The receiving-pipe is preferably provided with a damper, J, and also when extended to the outside of the building with a grating, K, covering the same.

The operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains.

To connect the drum with the pipes, the sleeves are screwed thereon beyond its ends. The drum is then placed in position and the sleeves secured in the opposite direction over the pipe ends and againstthe shoulders formed by the flanges (l 6, thus attaining a tight and perfect joint. The drum can be quickly and easily removed by disconnecting the sleeves from the pipe ends without interfering with the grate.

It will be apparent that the invention is equally as well adapted as a ventilator for use in warm weather.

I claim as my invention 1. The combination, with receiving and delivery pipes having their opposing ends provided with circumferential flanges, of a removable drum adapted to occupy the space between said ends and having its own ends screw-threaded, and sleeves provided with interior screw-threads, said sleeves being adapted to be disposed upon the ends of the drum and screwed over said pipe ends and against the flanges thereon, substantially as setforth.

2. The combination,with receiving and delivery pipes provided With smooth opposing ends and with circumferential flanges in rear thereof, of a removable drum adapted to occupy the space between said ends and having its own ends screw-threaded, and cylindrical sleeves provided with interior screw-threads at one end adapted to engage the ends of the drum, the remaining interior surface being smooth and adapted to be screwed over the corresponding smooth ends of said pipes and against the shoulder, substantially as set forth.

3. The combination, with a fire-place, of receiving and delivery pipes having their opposing ends projeeling therein at opposite sides and provided with circumferential flanges adapted to fit against the sides of the fire-place, a removable drum adapted to fit the space between said ends and provided at its own ends with exterior screw-threads, and connecting-sleeves provided with interior screwthreads and disposed upon the ends of the drum, said sleeves being adapted to be screwed over the pipe ends and against the flanges thereon, substantially as set forth.

4. The herein-described heating and ventilating apparatus, comprising the receiving and delivery tubes, the former being provided with a damper and the latter with a register or registers, the opposing ends of said pipes being formed with circumferential flanges, a removable drum adapted to occupy the space between said ends and having its own ends screw-threaded, sleeves disposed on the latter having a partiallyscrew-threaded interior surface for engaging the drum ends, the remainder of said interior surface being smooth and adapted to be adjusted over the corresponding ends of the pipes and against the flanges, substantially as and for the purpose set forth.
